1. Which type of work is primarily associated with the California C-17
Glazing Contractor classification?
A. Installation of underground utility pipelines
B. Installation of structural steel framing only
C. Installation of glass, glazing systems, and related glass or glazing
components within the scope of the classification
D. Installation of electrical distribution systems
The C-17 classification covers specialized glazing work, including the
installation of glass and associated glazing systems and components.
2. What is one of the most important considerations when selecting glass
for a particular installation?
,A. The glass manufacturer's logo
B. The required performance characteristics, safety requirements,
dimensions, thickness, type, and intended application
C. The color of the installation tools
D. The contractor's preferred brand regardless of specifications
Glass selection must be based on the project's functional, structural,
safety, energy, and design requirements rather than appearance alone.
3. What is safety glazing?
A. Glass that is installed only in ceilings
B. Glass that requires no inspection
C. Glass manufactured or treated to reduce the likelihood of serious injury
when broken
D. Glass that cannot break under any circumstances
Safety glazing is designed so that breakage produces less hazardous
conditions than ordinary annealed glass, making it appropriate for
specified hazardous locations.
4. Which type of glass is commonly recognized as safety glazing because
it breaks into relatively small particles rather than large sharp shards?
A. Annealed glass
B. Tempered glass
,C. Ordinary float glass
D. Wired glass in every application
Tempered glass is heat-treated so that, when it breaks, it generally
fractures into smaller pieces, reducing the severity of certain injuries.
5. What is a major characteristic of laminated glass?
A. It always breaks into large unsupported shards
B. It consists of glass layers bonded to an interlayer that can hold
fragments together after breakage
C. It cannot transmit visible light
D. It is made exclusively from acrylic
Laminated glass incorporates an interlayer between glass plies, helping
retain fragments after breakage and providing additional performance
characteristics.
6. Why is laminated glass often selected for applications where post-
breakage retention is important?
A. It eliminates all structural loads
B. The interlayer can help keep broken glass fragments together and
maintain a degree of barrier integrity
C. It cannot be scratched
D. It never requires framing
, The interlayer helps retain broken glass and can provide continued barrier
performance under specified conditions.
7. What is annealed glass?
A. Glass that has been heat-strengthened exclusively
B. Glass that has been cooled in a controlled manner during manufacturing
without being tempered or heat-strengthened
C. Plastic glazing
D. Laminated glass with no interlayer
Annealed glass is the conventional basic form of flat glass and does not
receive the strengthening heat treatment associated with tempered or
heat-strengthened glass.
8. What is heat-strengthened glass?
A. Glass that has been chemically dissolved
B. Glass that undergoes controlled thermal treatment to increase its
strength compared with annealed glass
C. Glass with no dimensional requirements
D. Glass made exclusively from acrylic
Heat-strengthened glass is thermally processed to increase strength while
generally retaining different breakage characteristics from fully tempered
glass.
